st: tabplot how to get rid of Graphs by ?

Dear Statalisters,
I have a small question: I would like to do some graphs with tabplot (from ssc).
Example code is:
webuse rate2, clear
tabplot pop, percent showval by(rada) note("") caption("") title("") subtitle("")
With this code I get a caption, note or whatever saying Graphs by Radiologist A's assessment.
Is there any way that I can get rid of this caption/note/title?
I know that I can use the Graph Editor to delete it and play the record again and again - but I think it would be smoother to do it within the code itsef.
Thanks for your help.
Marc
